AEMO sees the new build of renewable energy as critical to meet power supply shortfalls, noting in its latest report that more renewables will mean less need to burn gas for electricity. It also warns more gas will be needed if one of the country’s ageing coal generators fails.

Offshore wind auction results means that these projects are close to being subsidy-free, helping shift the conversation from renewables being expensive, towards how cheap, variable zero-carbon power can be integrated into the UK grid.

The COAG endorsement of the Finkel Review (apart from the CET) won’t mean much in the short term, but the generator reliability option might be a dumb idea. Meantime, smart companies are showing how to save costs with solar and storage.

The ability of wind power to deliver significant price falls in South Australia has been eroded by new rules that require more expensive gas generators to operate at times of high wind output. The days of “negative pricing” may be over.
